The concert will mark the 100th birthday of musical theatre icon, Alan J Lerner, who passed away in 1986. The playwright and lyricist won three Tony Awards and three Academy Awards for his work which included Brigadoon, Paint Your Wagon, Gigi and My Fair Lady with Frederick Loewe.

Robertson said: "Alan looked on lyric writing as a popular art form placing it somewhere between photography and woodcarving making him in my eyes a cross between Ansel Adams and Chippendale."

Ovenden added: "Alongside this stellar line-up, we'll look forward to doing justice to some of the greatest and best-loved musical theatre numbers".

The concert will be also be broadcast on BBC Radio 3 on Friday 22 June.
